About this map

The rugged interior of Mendocino County is defined by the winding course of the Ten Mile River and its numerous tributaries during the mid-1960s. The landscape is a network of named ridges including Bucha Ridge, Smith Ridge, and Ramsey Ridge, which separate deep drainages such as Bear Haven Creek and Smith Creek. Human presence is sparse, marked primarily by isolated agricultural and resource sites like O'Conner Orchard and a Gravel Pit in the southwest near Little Valley Creek.

A Gaging Station on the river suggests the importance of water monitoring in this heavily timbered region, while a labyrinth of Jeep Trails and standard Trails provides the only access through the gulches. Named for the prominent high point Dutchmans Knoll in the southeast, this survey captures the area before modern development, highlighting the complex hydrology of the South Fork Ten Mile River and its connection to the Pacific coast just to the west.
